Sequence of Operation

The following information will describe the Sequence of Operation for this water heater.

1.Switch power on to unit.

2.Thermostat calls for heat.

3.Variable Frequency Drive sends power to Blower.

4.Combustion Blower initiates air flow through water heater closing the Prover Switch.

5.Blower runs at low speed for 30 second pre-purge.

6.The Ignition Control provides power to the Spark Igniter and opens the Gas Valve.

7.Ignition Control maintains spark for up to 4 seconds and monitors Flame Sensor to determine if Burner is lit.

Lighting & Operating Label

8.If the Flame Sensor does not detect a strong enough flame, the Ignition Control shuts off the Gas Valve and allows the Blower to purge the unit for 30 seconds. At that time, the Ignition Control restarts with step 6. It will try and ignite the main burners 2 more times. If the unit does not light, the Ignition Control will wait 15 minutes and then restart at step 6. This cycle will continue until the unit lights or the power is shutoff to the unit.

9.If the Flame Sensor detects a strong flame, the Ignition Control will allow the unit to operate until the thermostat is satisfied.

10.Once the unit is satisfied, the Thermostat will shut off the Blower, Gas Valve and Ignition Control and the unit will be in standby mode until another call for heat is initiated by the thermostat.

See the flow chart on page 27 for more detailed information.
